QuEnc / AviSynth Hangs

[dwgsp]

I'm trying to convert an mpeg2 from PAL to NTSC. This is the first time that I have tried to use QuEnc to make this type of conversion (I have sucessfully used it for other tasks), and I'm having problems. The symptom is that everything hangs stops after about 20 seconds of video has been converted. It looks like AviSynth is hanging (confirmed by opening the avs file in VirtualDub).

Here's the avs script that I'm using, which was mostly copied from the AviSynth manual:

DirectShowSource("H:\Video/DrWho01x03_PAL.mpeg")
ConvertToYV12()
Bob(height=480)
BicubicResize(480, 480)
ChangeFPS(60000, 1001)
SeparateFields.SelectEvery(4,0,3)
Weave

Any suggestions will be much appreciated!

Thanks,
/Don

i'm guessing it's directshowsource's fault.

you can process mpegs (esp. those capped through DVB which i assume is your source) with DGindex and load them with mpeg2source.

audio can be processed separately - just drop it into your authoring app if you're not changing the speed of the video (oh, wait, you're doing SVCD - you might want to transcode the audio to mp2 if it's ac3).

however if this is the new series of Dr Who, it'll be progressive PAL. so no bobbing will be necessary - just drop that from the script and leave the rest.

if you don't mind re-encoding the audio, you can slow down the video to 24000/1001 and perform pulldown after encoding with quenc.

Mug,
Yep, it was directshowsource's fault. I took your advice and switched to using DGIndex/mpeg2source and all is well. The only thing that I did not do (yet) is drop the bob command. I will try that when I am ready to convert the next episode.

BTW, I'm doing all this so that I can watch these episodes on my non-hacked TiVo (I neglected to record them when they were recently broadcast).

Thanks again!
